Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 19, 2022The c.695C>T (p.A232V) alteration is located in exon 5 (coding exon 4) of the TXLNB gene. This alteration results from a C to T substitution at nucleotide position 695, causing the alanine (A) at amino acid position 232 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
